Application filed September 15, 1916.

T0 ZZ 'whom t may concern.'

Be it known that I, JOHN R. SoMnRs, a citizen of the United States,residing at Charlestown, in the county of Suolk and State ofMassachusetts, have invented certain useful Improwements in Gages, ofwhich the following is a specification, reference being had therein tothe accompanying drawing.

This invention relates to improvements in gages, one object of theinvention being the provision of a surface and depth gage attachment forcombination sets, whereby the device is quickly manipulated to bepresented at any one of the graduated portions of the scale and by meansof which the gage member may be positioned and held at such desiredpoint and at any desired angle.

A still further object of this invention is the provision of a gage ofthis character which is simple, durable and inexpensive in construction,and thoroughly efficient and practical in use.

In the accompanying drawings:

Figure 1 is a side elevation of the complete device.

F ig. 2 is a detail view of the attachment per se.

Figs. 3, 4 and 5 are detail views thereof.

Referring to the drawings, the numeral 10 designates the rule member ofthe device, and 11 the handle member thereof, both of which are of usualconstruction.

Mounted for sliding movement upon the member 10 is a. frame 12 which ispreferably made from a single piece of metal and provided with thereceiving slot 13 and with the split end 14, so that the device 12 willact as a clamp to resiliently grip the member 10.

The split end of the member 12 is pro- Speccation of Letters Patent.

member 12, this scriber may be adjusted at.

any desired inclination -or position before being clamped, while themember 12 which is provided with the oppositely disposed observationslots 23 may also be adjusted so as to place the indication marks 24thereof adjacent any graduation of the member 10.

What I claim as new is:-

In combination a ruler having indicated graduated marks on oppositesides, a rectangular member having a transverse slot through which theruler slidably projects and having formed upon opposite sides thereofelongated slots intersecting the plane of the first named slot so as toprovide sight openings upon opposite sides of said member to expose theindications upon the sides of a ruler, said last named elongatedslotbeing formed at opposite ends of the slot and at opposite sides ofsaid member with longitudinally disposed beveled edges forming knifeedges with the opposing end edges of said slot, said beveled edgesprojecting at their outer ends beyond the opposite longitudinal edges ofthe ruler, the knife edges of said beveled edges being segmental andsaid beveled edges having a line eX- tending across its length centrallythereof adapted to check up with any of the graduated marks on saidruler.

In testimony whereof I aix my signature.
